The API service did not reliably service new image render requests starting at 21:36 GMT on August 29, 2017 and 14:05 GMT on August 30, 2017. This was caused by 3rd party that is used to resize images.

The service was temporarily restored to full functionality at 00:42 GMT on August 30, 2017 and permanently restored at 18:45 GMT on August 30, 2017.
